MIT engineers have designed a “brain-on-a-chip,” smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as…
Rife with obstacles and occlusions, terrestrial environments potentially helped give rise to planning circuits in the brain. New simulations show that living among land’s rich…
Feeling disconnected from others is reflected by how the brain represents relationships. Social media sites aren’t the only things that keep track of your social…
Three-dimensional virtual reconstruction of the braincase of the ankylosaur Bissektipelta archibaldi. Bones are semi-transparent and the internal contents of the endocranial cavity are seen. Pink…
Billiard-like break shot to cell-membrane structures triggers brain’s loss of consciousness from anesthesia, scientists find. Surgery would be inconceivable without general anesthesia, so it may…
Frontoparietal activation reflects individual working memory abilities. Credit: Rosenberg et al., JNeurosci 2020 Brain network activity predicts working memory abilities during development. A child’s unique…
Credit: Nathan Johnson/PNNL A molecule commonly produced by gut microbes appears to improve memory in mice. A new study is among the first to trace…
Remote, brain region-specific control of choice behavior with ultrasonic waves. Noninvasive pulses of ultrasound waves aimed at specific regions in the brains of macaque monkeys…
Strengthened amygdala pathways increase aggression, may be targets for PTSD treatment. Traumatic stress can cause aggression by strengthening two brain pathways involved in emotion, according…
[embedded content] New research from a team of international scientists shows how swelling associated with brain and spinal cord injury can be stopped using a…
[embedded content]2-photon calcium imaging (5x speed) of the activity responses of neurons in hippocampal area CA1 of a mouse as it learns to associate a…
The Allen Mouse Brain Common Coordinate Framework (CCFv3), a 3D reference atlas, is based on an average of the inherent fluorescence in the brains of…

The device structure at a molecular level. The gold nanoparticles on the bottom electrode enhance the field enabling an ultra-low energy operation of the molecular…
A graphic depiction of protein nanowires (green) harvested from microbe Geobacter (orange) facilitate the electronic memristor device (silver) to function with biological voltages, emulating the…
Reconstructed sagittal 5-mm orthogonal midline images in the brain using the sagittal three-dimensional T1weighted data set. (a) Preflight baseline image and (b) matching postflight image…
A new form of magnetic brain stimulation rapidly relieved symptoms of severe depression in 90% of participants in a small study conducted by researchers at…
Brain imprints in fossil skulls of the species Australopithecus afarensis (famous for “Lucy”, and the “Dikika child” from Ethiopia pictured here in frontal and lateral…
